基于Simulink的牛头刨床运动分析仿真及优化

Kinematic Analysis and Simulation and Optimization of Shaper based on Simulink

牛头刨床是一种具有急回特性的金属切削类中用于刨削加工的机床,其关键机构为六杆机构。运用矢量解析法对牛头刨床六杆机构进行了运动学分析,利用Simulink反复求解机构运动微分方程进行运动学仿真,通过积分获得速度以及位移。针对机构的实际应用的要求,确定优化目标,运用Simulink软件中Parameter Estimation模块对参数进行优化,参数优化取得成功,此法简便易行,同时也为其他往复运动机械的优化设计提供了值得参考的设计思路和优化方法。

The shaper is a planing machine for quick return characteristic in metal cutting, the key mechanism is six-bar mechanism. The vector analytical method is used for kinematic analysis of shaper six-bar mechanism and tile simulation software package Simulink is used to solve the dynamic differential equation of the mechanism repeatedly, so as to carry out the kinematics simulation. Velocity and displacement is obtained by integration. The optimization objectives of the mechanism are determined according to the requirements of the practical application. Optimization of parameter is successful by using Parameter Estimation module in Simulink software package. This method is simple and easy to operate, but also provides a valuable reference of design ideas and methods for the optimization design of reciprocating machinery.
